Non-organic food production makes wide use of pesticides which can pollute water, the environment and make their way into our food chain. Many pesticides don’t just kill the target pest. They can affect other wildlife and the environment by either direct poisoning, contaminating water courses or disrupting ecosystems. In organic farming, natural methods are relied upon to control pests and disease. These include well-designed crop rotations, encouraging natural predators, and developing good soil and healthy crops which have natural resistance to pests and diseases.
